Used for high-altitude and low-voltage (high-altitude) simulation testing of batteries, the tested batteries are tested under negative pressure of 11.6kPa (1.68psi) for 6 hours. It is required that the tested batteries cannot explode, ignite, smoke, or leak to be qualified. The equipment can automatically control the test cycle (such as 6H), monitor the pressure changes inside the box throughout the process, and achieve automatic termination of the test
